VALVE.

SPECIFICATION forming part of Letters Patent No. 638,362, dated December5, 1899.

Application filed August 31,1899. Serial No. 729,052. (No model.)

To all whom it may concern.-

Be it known that I, CHRISTIAN SEAHORN, a citizen of the United States,residing at Schenectady, in the county of Schenectady and State of NewYork, have invented certain new and useful Improvements in Valves; and Ido hereby declare the following to be a full, clear,' and exactdescription of the invention, such as will en able others skilled in theart to which it appertains to make and use the same.

My invention has relation to improvements in valves of that kind orstyle adapted to be interposed in steam or water pipes to direct,deflect, and control the course of the fluid as may be desired and whichmay be interposed in a system of heating apparatus or radiators.

The object is to provide an improved valve of the kind named and for thepurposes intended which is simple and durable in construction andefficient and certain in operation.

The invention consists in certain novel constructions of parts and theircombination, as will be hereinafter fully described, and particularlypointed out inthe claims.

I have fully and clearly illustrated my improvements in the accompanyingdrawings, forming a part of this specification, and wherein- Figure 1 isa central, vertical, and longitudinal section through the casing andvalve,showing the valve or turning-plug turned so as to permit a freepassage of the fluid through the main passages of the casing. Fig. 2 isacentral,vertical,and longitudinal section through the casing and valve,showing the valve or turning'- plug turned to shut off the flow throughthe pipe-channels of the casing and so that the fluid will be directedthrough the end passages of the valve. Fig. 3 is a detail view of thevalve or turning-plug removed from its seat in the casing.

Referring to the drawings, A designates a cast or malleable metal casingof such size, dimensions, and capacity as will adapt it to the purposesintended. The lower portion of the casing consists of a chamber having avertical partition 1, dividing it equally, and provided with aninlet-opening 2and an outlet-opening 3, the ends of the openings beingsuitably screw-threaded to connect with pipe-sections (not shown)leading to and from the casing.

In the upper portion of the casing is formed a tubular valve-seat 4,arranged at right angles to the ways 5 5 in the casing, which ways openinto the valve-seat substantially as indicated in the drawings, theupper end of the partition 1 beingalso coincidentally curved topartially encircle and set about the body of the valve. At one end ofthe valve-seat is an opening 0, through which the stem of the valveprojects, as shown, and adjacent to this end is a supply-passage 7,extending through a coupling-piece 8, suitably screw-threaded, andwhereby the desired connection and communication maybe made to aradiator or other device to which my valve is applicable. The other endof the valve seat or chamber is open, as at g, providing areturn-passage and suitably screw-threaded, so that it may be closed bya screw-cap or connection made to a return-pipe.

B designates the valve or turning-plug,fitted snugly in the valve seator chamber to turn therein and having its end or stem 10 extendingthrough the opening 6 and provided with a suitable handpiece 11, securedthereto, by which the valve may be turned as desired.

Through the body of the valve are formed two passages or ways 12 12inclined in opposite directions, as indicated in the drawings, the waysbeing separated by the inclined parth tions 13 13 terminatingsubstantially at the longitudinal middle of the valve-body, as at m, achamber or way 14 being thus formed between said ways, which chamberconstitutes a passage between the pipe conduits or passages in thecasing for the purposes of conducting the fluid from the inlet source tothe outlet source or pipe. It will thus be perceived that when the valveor turning-plug is turned to bring the inclined ways or passages intothe position shown in Fig. 1 the fluid is free to pass from theinlet-passage to the outlet-passage in the casing and that when thevalve is turned into the position shown in Fig. 2, with apex or ridge ofthe inner inclines on the partition wall, the fluid will have freepassage through the way adjacent to the stem end of the valve and thencethrough the opening and through whatever medium or pipe provided andback through the return opening or passage out through the mainoutletpipe.

passages adapted to bring into commu nication the inlet and outlet andsupply and re turn passages respectively when the plug is in oneposition said plug being also provided with a third passage between theoppositelyinclined passages adapted to bring into com- ;munication theinlet and outlet when the plug is turned in a substantially oppositeposition, the arrangement of parts of the device being such that thevalve either allows fluid to flow through, or short-circuits theradiator to which it may be attached.

2. A radiatorfitting comprising a casing having an inlet and an outletseparated by a partition and adapted to communicate with afluid-circulating system and a valve-chamher at substantially rightangles to the inlet and outlet having a supply-passage andreturn-passage adapted to communicate with a radiator,a tu rn-plug insaid chamber provided with oppositely-inclined passages adapted to bringinto communication the inlet and outlet and supply and return passagesrespectively when the plug is in one position, said plug being alsoprovided with a third passage between the oppositely-inclined passagesadapted to bring into communication the inlet and outlet when the plugis turned in'a substantially opposite position, the arrangement of partsof the device being such that the valve either allows fluid to fiowthrough, or short-circuits the radiator to which it may be attached.

In testimony whereof I affix my signature in presence of two Witnesses.
